Eden

Creates a new map location on the main map in the center of the lake called Eden. To enter Eden, you must have a cumulative total of 50 airship stars or higher and pay 800k coins.

To unlock Eden's functions you need to first do some of the Eden Mazes (available just once) and complete repairs for them. Once you've completed the repairs you'll unlock the repeatable Eden's Land maze.

Once the Tech Hall is completely repaired, you'll unlock the ability to Research. Research is needed to unlock Space as well as 4 new parasitic Gumballs, more clones and much more.

Research is currently divided into 6 tabs, with the last one being unlocked through an item in Space. Also note that some research requires you to increase your Civilization level by constructing Plane Wonders.
